Orphan Black is one of the most critically-acclaimed and fannishly-popular SF TV series to debut in the last few years, and is notable both for being a strongly feminist narrative and for sticking (more or less, so far) to a plausible depiction of biological sciences. In the season one finale, the two themes are linked: “We have to control our biology”, one of the clone-sisters asserts. Bearing this imperative in mind, how do the show’s feminism and science interact and inform one another? How successful is the show at balancing commercial and political narrative goals?
